Before You Start

1. Read through this Installation Guide in its
entirety before starting installation of your
iDevices® Thermostat or removal of your

dangerous and can damage your iDevices

Thermostat and HVAC system. If you’re not

®

comfortable performing the installation,
contact a local HVAC contractor.

2. Turn the power to your HVAC system
and old thermostat OFF!

3. Ensure you do not have electric baseboard
heating. The iDevices® Thermostat is not
compatible with these systems.

4. Check that your mobile device is compatible
with the iDevices® Thermostat at
iDevicesinc.com/Compatibility.

5. If this is a new installation, you will need to
install the iDevices

®

Thermostat 4 – 5 feet

above the oor, in accordance with applicable

building codes. It should be installed in an

area with good airow. Avoid areas behind

doors, near corners, heating or cooling
vents, heat generating devices, or
direct sunlight. This Transmitter must be installed to

provide a separation distance of at least 20 cm from all persons

Abbreviations

HVAC: Heating, Ventilation, and Air
Conditioning system

HP: Heat Pump System. This type of HVAC
system uses a compressor with a reversing valve
to provide both heating and cooling capability.

HE: Electrically heated central heating system.
This system uses an electric heating element
along with a fan and ducting. Sometimes used as
AUX/Emergency heat with a heat pump system.
Electric baseboard heaters are not included in this
system type.

HG: Fuel-red central heating system. This system

uses a gas or oil burner along with a fan and
ducting, or a hot water baseboard system. Can be
used as a standalone heating system or as AUX/
Emergency heat with a heat pump system.

O/B: This option selects the type of reversing
valve for heat pump systems. An “O” reversing
valve is energized when cooling, and a “B”
reversing valve is energized when heating.

Installation Details

1. Gather the tools you will need and check
that your iDevices

®

Thermostat came with the

necessary components (see page 4).

Do not select COOL mode if the outside temperature is below
50ºF (10ºC). This could damage the cooling system.

Warnings And Safety Information

2. Test your existing system. Using your old
thermostat, turn on the heating/cooling
functions (if applicable) to verify everything is
functioning normally.

3. If you have a heat pump system, check the
settings on your old thermostat and make
a note whether you have an “O” or “B” type
reversing valve.

4. Turn the power to your HVAC system OFF at
the breaker box or the main switch controlling
your heating/cooling system.

5. Conrm that the power is OFF by adjusting

the temperature on your old thermostat and
waiting to ensure your system doesn’t turn on.

6. Carefully remove the faceplate of your
old thermostat.

7. Take a picture of your old thermostat’s wire
arrangement to reference later on.

8. Make note of the current locations of each
